This article describes bridge configurations of different pressure sensors, when each can and cannot be used, and the pros and cons of each. Introduction Wheatstone bridge is the core of Merit Sensor’s pressure sensors and is comprised of a group of four resistors on a silicon etched diaphragm. When pressure is applied to the diaphragm, the resistors […]
Since manufacturers of medical equipment encounter constant pressures to balance cost and quality, pressure sensors present developers with contradictory requirements that can result in dangerous compromises. Pressure sensors pose a common reliability challenge that force manufacturers to depend on expensive ongoing maintenance and component replacement to work around the inherent short lifetime of the sensor. […]
A number of pressure sensor applications in harsh environments such as industrial, automotive, aerospace and even medical equipment present developers with contradictory requirements that result in expensive compromises. Generally, these sensors are employed to measure flow, level and pressure of harsh fluids such as refrigerant, oil, gas or other caustic solvents that can damage the […]
The choice of components in a system, including pressure sensors, is significantly affected by price efficiency. If the components exactly fit into the application without the addition of irrelevant cost or value, then it is possible to achieve the best results. The research on various sensor module configurations led to the discovery of an uncompensated […]
Examples of a basic automobile go back as early as the 1700s, with the design and engineering of steam-powered engines, built to transport humans. By 1806, the automobile industry started the production of engines running on fuel such as gasoline and petrol. Since 1985, the revolution of car design has resulted in creating a machine […]
Take a look at Merit Sensor’s product portfolio, and you will see that the pressure sensors are available fully compensated, passively compensated, and uncompensated. Let’s briefly review the differences. When signal conditioning is used to compensate for a sensor’s non-ideal output, the sensor is considered fully compensated. When laser-trimming technology is used to change a sensor’s […]
We would like to thank you to spend few moments to read our announcement as, with the recent acquisition of First Industries by Alcyon Electronique, we are delighted to inform you that Alcyon Electronique, a company located in Beynes, in the Paris region, is now our distributor in France, Belgium, Spain and Portugal. Following on from […]
To evaluate the quality and performance of a MEMS silicon die, customers must rely on specifications, at least until they can test parts for themselves. This article will discuss the most common specifications related to these pressure-sensor dies. The primary thing to understand about MEMS dies is that when they are exposed to either pressure […]
After 30 years of designing and manufacturing pressure sensors, we at Merit Sensor are happy to see our products used in so many applications. In the past year we were fortunate to support the surge in global demand for mechanical ventilators (read more here), while we continued to support other medical applications, such as blood-pressure […]
At the heart of every MEMS pressure sensor is a MEMS silicon die. Merit Sensor owns and operates a wafer fab, where it produces all of its own MEMS die. Packaging a MEMS die requires specialized equipment and skills to handle the small and sensitive die and to perform delicate wire bonding. Therefore, many customers […]
